Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers (if applicable) using a flathead screwdriver.
2. Loosen the lug nuts with a lug wrench.
3. Lift the vehicle using a hydraulic jack and secure it with jack stands.
4. Remove the lug nuts and take off the wheel.
5. Inspect the tire for uneven wear, bulges, or foreign objects.
6. If damage is found, replace the tire with a new one of the same specifications.
7. Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and torque the lug nuts to the manufacturer’s specifications (usually around 100 lb-ft).

3. Wheel Balance and Alignment

Sub-steps:
1. Take the vehicle to a professional tire shop for wheel balancing.
2. Have the technician perform a wheel alignment, adjusting the camber, caster, and toe angles according to the manufacturer's specifications.

4. Drivetrain Inspection

Sub-steps:
1. Visually inspect the driveshaft for any signs of damage or misalignment.
2. Check the motor mounts to ensure they are intact and not worn.
3. If any components are damaged, replace them with OEM parts.
